HEC-RAS Overtopping Analyses 1 INTRODUCTION The Buena Vista Channel Maintenance District (District) was formed in 1989 and is administered by the City of Carlsbad. The District boundaries include the Buena Vista Creek channel from the Jefferson Street Bridge upstream or east to the South Vista Way Bridge (see Figure 2 after this report text). One purpose of the District is to provide an effective, consistent means of clearing the channel between the bridges. The Vicinity Map in Figure 1 shows both streets and the channel. State Route 76 is north of the channel and the Plaza Camino Real shopping center is south of the channel. The Vicinity Map was created from the Federal Emergency Management Agency’s Flood Insurance Rate Map (Map No. 06073C0762G dated May 16, 2012). The FEMA 100-year floodplain is shaded in blue on the Vicinity Map. Figure 1. Vicinity Map The Buena Vista Creek channel within the District boundaries serves as a flood control channel with a trapezoidal cross-section containing a natural bottom and riprap-lined banks. The channel was relocated to its current alignment in 1979 to allow construction of the Plaza Camino Real shopping center parking lot. The channel roughness has increased over time due to vegetative growth in the natural channel areas. The increased roughness gradually increases resistance to water flows and jeopardizes the flood control capacity of the channel. Since the channel was completed, the north half of the channel has been dredged twice to assist in restoring the channel capacity, once in 1993 and again in 1997. In 2002, the City evaluated the need, frequency, and methods for maintaining the Buena Vista Creek channel within the District boundaries. Hydraulic studies were prepared to analyze the flood control capacity within this portion of the stream channel. The studies determined that during a 100-year storm event, flows would overtop the channel banks and inundate the adjacent parking lots in the District. Therefore, in 2003, the City approved an ongoing maintenance program to reduce flooding within the District properties. In 2004, the City initiated a 5-year 2 maintenance program that consists of hand removal of vegetation within the northern half of the channel between the South Vista Way Bridge and the Coastal Zone boundary. The Coastal Zone boundary is approximately 900 feet east of Jefferson Street (see the HEC-RAS Work Map in Figure 4). This report contains hydraulic analyses for reevaluation of the need, frequency, and methods for maintaining the Buena Vista Creek channel within the District. Since initiation of the channel maintenance program in 2004, the portion of the District channel within the Coastal Zone, which has not been maintained since the dredging in 1997, has accumulated sediment and experienced increased vegetative growth. The sediment and vegetation impedes the channel outlet and upstream channel capacity. This report analyzes the current conditions, and then alternatives for vegetation removal from the northern half of the channel from the upstream face of the Jefferson Street Bridge, which is within the Coastal Zone, to the downstream face of the South Vista Way Bridge. The goal of the analyses is to analyze vegetation removal alternatives over specific periods of time in order to assess flood protection benefits for the properties in the District while maintaining biological functions and values within the creek. HYDRAULIC ANALYSES Several HEC-RAS hydraulic analyses were performed for Buena Vista Creek and used to assess the current conditions as well as maintenance alternatives outlined by Dudek. The following describes the input data. Each of the HEC-RAS analyses extends from Buena Vista Lagoon immediately downstream of Jefferson Street to the downstream face of El Camino Real. The 100-year analyses were based on the Federal Emergency Management Agency’s 100-year flow rate in Buena Vista Creek of 8,500 cubic feet per second (the FEMA 10-, 50-, and 500-year flow rates are 2,000; 5,600; and 19,000 cfs, respectively). The starting water surface elevations were based on normal depth near the lagoon. The HEC-RAS cross-sections were created from 2005 topographic mapping provided by the City of Carlsbad. The mapping is on NAVD 88 vertical datum. The cross-sections were converted to NGVD 29 vertical datum (NGVD 29 = NAVD 88 – 2.23’) to be consistent with the FEMA analyses. The mapping and cross-sections are shown on the HEC-RAS Work Map in Figure 4. Jefferson Street and South Vista Way Bridges were modeled based on the topographic mapping, as-built plans, and site observations. A 100-year hydraulic analysis was performed initially for the current conditions. A site visit was made to assess the current vegetative growth in the study reach. The majority of the study reach contains moderate to dense vegetation although some small portions were concrete-lined with no vegetation. On the other hand, some segments of the concrete-lined channel supported vegetation that established from soil that deposited on the concrete. In order to reflect the channel cover, the roughness coefficients were assigned values ranging from 0.014 (concrete-lined channel) to 0.10 (channel with trees and dense vegetation). The 100-year results are included in Appendix A, which contains the tabulated results and plots of each cross-section. A review of the cross- section plots shows that the 100-year water surface exceeds the channel banks at many locations. Therefore, the channel does not have capacity for the 100-year flow under current conditions and 3 adjacent areas beyond the channel and within the District will experience flooding. The developed areas that can experience flooding are the shopping center parking lot, retail areas and the sewer treatment plant along the northerly portion of the parking lot, and the existing development north of the channel along South Vista Way. The current conditions results are summarized Table 2 included after this report text. Table 2 provides each cross-section’s top of bank elevations along the left (south) and right (north) channel banks. A portion of the area beyond the right channel bank is undeveloped or along the State Route 78 embankment. Right bank cross-sections were not included in Table 2 for these areas because the District boundary either follows the freeway embankment or contains natural areas that are undeveloped. Table 2 also includes the 100-year water surface elevations to allow a comparison of the water surface elevations with the top of bank elevations. The difference between the water surface elevations and top of bank elevations are provided for each cross- section. The red numbers indicate the water surface is below the bank and contained in the channel, while the black numbers indicate were the water surface will overtop the bank. The hydraulics of water overtopping an embankment can be difficult to model particularly when the overtopping can occur at various locations. The HEC-RAS modeling performed for this report use a streamlined approach where the difference values may not represent the actual overtopping depth because the flow spreads once it overtops, but since the same approach is used for each analysis in this report, the results allow a relative comparison of the alternatives. The difference values in Table 2 indicate that overtopping of the channel banks will occur at many locations under existing conditions. A subsequent analysis was performed assuming the entire channel between Jefferson Street and South Vista Way was maintained at one time. Although the entire channel will not be maintained, this analysis was performed because it provides an indication of the maximum channel capacity. The roughness coefficient was set at 0.035 to reflect the areas with channel maintenance. The results are included in Appendix A and Table 2. The cross-section plots in Appendix A and the difference values in Table 2 indicate that the 100-year flow is contained within the fully-maintained channel at most locations. Some overtopping will occur near Jefferson Street. The next analysis assumes that the northerly half of the entire channel between the two bridges was maintained. The 100-year results included in Appendix A and summarized in Table 2 show that flow will be contained within the majority of the left bank. The overtopping that occurs along the left bank will have rather shallow depth. Overtopping can occur along the right bank, but at a much smaller magnitude than under current conditions. Therefore, while 50 percent channel maintenance does not provide the level of flood protection compared with the entire channel being maintained, it provides significant benefits over current conditions. Three more hydraulic alternatives were analyzed assuming maintenance of the northerly half of the channel between the two bridges. The alternatives are based on maintenance occuring over a 3-, 5-, and 6-year period. Each alternative assumes that maintance begins near Jefferson Street then progresses east in equal intervals towards South Vista Way in subsequent years. For example, the 5-year maintenance plan divides the north half of the channel into five equal segments between the two bridges. At the onset of maintenance, the westerly 1/5th channel 4 segment is maintained. After the first year, the next upstream 1/5th is maintained. After the second year, the next upstream (middle) 1/5th is maintained, etc. The three alternatives consider regrowth of vegetation as each subsequent year passes. For example, under the 5-year plan, the initial westerly 1/5th area will experience some regrowth by the time the second 1/5th area is maintained. The intial and second 1/5th areas will experience some regrowth by the time the third 1/5th area is maintained (the intial area will have greater regrowth than the second area) and so on. The regrowth is modeled in the analyses by adjusting the roughness coefficients to gradually higher values to reflect an increase in vegetation over time. According to Dudek, the channel vegetation can be classified into two categories (fresh water marsh and southern willow scrub) with differing growth rates. Freshwater marsh (FWM) will reach approximately one-half of its mature size after 12 months. In terms of density, FWM would have 50 percent density after one year, 75 percent after two years, and 100 percent after three years. For southern willow scrub (SWS), Dudek estimates that the species grow to an average 5 feet high after one year, 8 feet at two years, 12 feet at three years, 15 feet at four years, and 20 feet at five years. Full mature tree height and trunk diameters will not be met for approximately 10 to 20 years after planting. The percent cover for SWS is estimated to be 25 percent after one year, 40 percent at two years, 60 percent at three years, 75 percent at four years, and 90 percent at five years. These estimates can change based upon variable environmental conditions. From the physical characteristics of these two vegetation types, roughness coefficients were selected as listed in Table 1. Figure 3 delineates the various vegetation types. The Diegan coastal sage scrub is categorized as FWM, while mulefat scrub and ornamental are categorized as SWS. The southern coastal salt marsh, disturbed habitat, and open water will not change roughness with maintenance. Year Fresh Water Marsh Southern Willow Scrub 1 (Initial Removal) 0.035 0.035 2 0.045 0.044 3 0.053 0.051 4 0.060 0.056 5 0.065 0.061 Table 1. Time Variation of Roughness Coefficients For each alternative, multiple 100-year analyses were performed to determine the annual results for each maintenance scenario. Three analyses were performed representing each year of the 3- year maintenance plan, five analyses were performed representing each year of the 5-year plan, and six analyses were performed representing each year of the 6-year plan. The results are included in Appendix B, C, and D and Tables 3, 4, and 5, respectively. The results indicate that all of the alternatives reduce the flooding potential over current conditions. The 3-year plan provides greater flood protection than the other two alternatives. The results from the 5- and 6- year plans are relatively similar. Under all of the alternatives, overtopping of the channel banks can occur in the reach near South Vista Way, but the water surface elevations will be much lower 5 than current conditions, which indicates that overtopping will occur during a larger storm event under the alternatives in comparison to current conditions. Additional analyses were performed to determine the flow rate at which the overtopping will begin to occur at any location along the channel between the two bridges. For all of the analyses, this occurs at the right bank of cross-section 1.597, which is near the Monhacky Animal Hospital. The overtopping analyses are included in Appendix E and summarized in Table 6. The results indicate the creek flow will begin to overtop the channel under current conditions during a 20-year storm event. Under the maintenance alternative, this can increase to over a 40-year storm event. CONCLUSION Hydraulic analyses have been prepared for Buena Vista Creek within the Buena Vista Channel Maintenance District. The analyses show that a fully maintained channel approaches capacity for the 100-year storm flows. On the other hand, under current conditions the 100-year flow will exceed the channel capacity at many locations and the water will begin overtopping the channel during the 20-year flow event. Several maintenance alternatives were analyzed. Each alternative provides a higher level of flood protection than current conditions and initial channel overtopping can be increased to over a 40-year event. Each alternative will minimize the potential for flooding beyond the channel as well as the potential for pollutants from being conveyed from the adjacent parking areas, streets, etc. From a solely hydraulic standpoint, a shorter duration maintenance plan provides more flood protection than a longer term plan. However, channel maintenance must balance hydraulic benefits with environmental goals of preserving vegetation. As a result, a 5-year maintenance plan is being proposed. This will allow vegetation to contiously establish in the channel, while providing significant flood protection benefits. 6 River Station Bank Elevation, ft Current Conditions, ft.
